When revenue per bit starts falling and cost per bit starts increasing, it’s time to think about alternative strategies to expand Transmission/IP network. As IP is predominant traffic in Transmission networks, therefore …
Are you concerned about latency in your data center links running over optical network ? Or, are you planning for Data Center Interconnectivity in near future and want to …
What your DWDM vendor did not tell you about latency for your Data Center Interconnect Read More »
OSNR ( Optical Signal to Noise Ratio) is a critical and important parameter in high speed DWDM links. If OSNR is not good it will seriously affect the distance reachability …
As data rates increase beyond 10G, the requirements for OSNR become stringent. This is because the advanced modulation techniques used at higher bit rates require higher OSNR performance. Low OSNR …
Soft Decision FEC ( SD FEC) versus Hard Decision FEC Read More »
The debate still lingers on. When it comes to protection and re-routing on High speed links, what is the benefit of using Optical ASON versus Electrical ASON. The Optical ASON relates …
The debate whether there is a market for 100G direct detection systems which are essentially Non Coherent is interesting. ADVA is on one side while the rest of industry on …
